Evaluation and improvement of frost durability of clay bricks
… of the brick was studied using laboratory freeze-thaw test. As the time and facility requirements necessary for the unidirectional freezing test were beyond the constraints which existed in this research, an accelerated omnidirectional freeze-thaw test was used. This fact must be considered …

Evaluation of Laboratory Durability Tests for Stabilized Subgrade Soils
… to compare selected laboratory durability tests available for assessing stabilized subgrade materials. Improved understanding of these tests is needed to enable more objective selection of durability tests by design engineers and to facilitate more meaningful comparisons of data obtained …

Evaluation of Laboratory Durability Tests for Stabilized Aggregate Base Materials
… to compare selected laboratory durability tests available for assessing stabilized aggregate base materials. The laboratory research associated with this project involved two granular base materials, three stabilizers at three concentration levels each, and three durability tests in a …

EFFECT OF CRACK-REDUCING TECHNOLOGIES AND SUPPLEMENTARY CEMENTITIOUS MATERIALS ON SETTLEMENT CRACKING OF PLASTIC CONCRETE AND DURABILITY PERFORMANCE OF HARDENED CONCRETE
… durability of concrete subjected to freezing and thawing were evaluated. The study of settlement cracking included 86 concrete mixtures containing internal curing (IC), a shrinkage reducing admixture (SRA), optimized and non-optimized aggregate gradations, or the supplementary cementitious …

Deterioro del hormigón sometido a ensayos acelerados de hielo-deshielo en presencia de cloruros
… de sales fundentes. Se han extraido probetas testigo de los puentes y sobre ellas se realizaron ensayos para conocer la resistencia a compresión, la porosidad y distribución porosa, asi como el grado de deterioro de los hormigones por la penetración de cloruros. El trabajo realizado pone de …

Influencia de las condiciones de curado en el comportamiento del hormigón sometido a ciclos hielo-deshielo
… pérdida de peso y cambios de longitud. ABSTRACT Freeze–thaw process is one of the main causes of concrete degradation in cold regions. In central and eastern Europe, the climatic conditions in the winter season are particularly severe for concrete construction. The successive freezing/thawing …

Dairy ingredients-based emulsions and beta-carotene delivery
… After passing through the simulated gastrointestinal tract (GIT) digestion, initial droplet size significantly influenced the emulsion properties (e.g., droplet size and distribution and surface charge), but did not significantly affect the bioaccessibility and cellular uptake of β-carotene. …
